A Linear Cutting Stapler Adopting a New Transmission Mechanism

Abstract

The invention relates to a linear cutting stapler adopting a new type of transmission mechanism, including a fixed splint, a nail abutment seat assembly, a closing splint and a transmission mechanism, wherein: the front part of the fixed splint is equipped with a nail bin assembly, a nail abutment seat assembly and a closing splint The splints are rotatably connected with the fixed splints; the transmission mechanism includes a support link, a push knife link and a knife rack; The rear end of the rod is rotatably connected to the fixed splint, and the front end of the supporting link is rotatably connected to the rear end of the push knife link; Installed in the fixed splint. The invention has a compact and reasonable structure, is light and flexible, can complete the cutting and suturing operation with one hand, and the operator hardly directly touches the wound, so it is more suitable for popularization and use.

Description

technical field [0001] The invention relates to a surgical medical instrument, in particular to a linear cutting stapler with a novel transmission mechanism. Background technique [0002] The linear cutting stapler has two functions of suturing and cutting. While suturing the wound, excess tissue is removed. The linear cutting stapler has been widely used in surgical wound suturing, internal tissue suturing and cutting. Existing linear incision stapler generally comprises upper and lower two jaws, and is used for closing the closing handle of upper and lower jaws, and the staple bin and the nail abutting seat that are arranged on the front end of upper and lower jaws relatively, are located at The firing piece and the cutting knife in the staple cartridge and can move relative to the staple cartridge at the same time, and the push torque for driving the firing piece and the cutting knife to move. Staples are arranged in the staple cartridge, and the firing piece pushes the ...

AI Technical Summary

Problems solved by technology

[0004] 1. Two hands are required to operate at the same time to complete the cutting and suturing;

[0005] 2. When pushing and twisting, the operator's hand is easy to enter the wound;

[0006] 3. The transmission mechanism of firing and cutting adopts a gear and rack structure. The firing and cutting of this structure are continuous, and firing and cutting cannot be performed step by step. Moreover, this structure cooperates with the trigger and cannot be realized by pressing. firing and cutting

[0007] This shows that the above-mentioned existing linear cutting stapler obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
